Visualizing Walmart's Growth Over Five Decades

My brother sent me this link a few weeks ago and I’ve watched it about 10 times since because I’m just in awe of it. Someone took the time to graphically plot the growth of Walmart in the United States from 1965 to 2007. It takes about 5 seconds to load up once you see the map, but once it starts going – hold on to your hats. A few stores pop up per year in the 60’s, but by the time you get to the 80’s there are hundreds of stores popping up per year and by 2007 you have over 3,000 points showing up on the map. You don’t have to do anything other than click this link and sit back and watch. The whole thing takes about one minute.
